Scrum does not say “only focus on output”, but, unfortunately, humans will optimize for what they measure.
If you worry about story points & hitting your estimations, that’s what is going to consume your attention. That is what you and your team will optimize for.
And that is the core critique of Scrum as it is practiced: That it focuses a product team’s attention so heavily on delivery — on building lots of features quickly & efficiently — that teams fail to focus on spending time to discover what the right thing to build is.
The [Silmarils] are good; their making was at least potentially innocent; but afterward arose a lust for owning and controlling that led to great tragedy… The aspect of humanity which the elves represent most fully – both for good and ill – is the creative one.”
And this is why “making” in and of itself is not the answer to our decadent moment. “Love of things, especially artificial things, could be seen as the besetting sin of modern civilisation, and in a way a new one, not quite Avarice and not quite Pride, but somehow attached to both” – and this is the Fëanor Temptation. It is in light of this temptation that I advocate repair, which is a mode of caring for what we have not made, but rather what we have inherited. We will not be saved by the making of artifacts — or from the repair of them, either; but the imperative of repair has these salutary effects: it reminds us of our debt to those who came before us and of the fragility of human constructs.
